Leetcode for DevOps

Have you ever been asked a Leetcode type question during an interview? I only had one DevOps interview and it was mostly about Linux, CICD, Containers, and IaaC stuff, but that was a small company. I'm curious do bigger companies ask this Leetcode kind of questions?

Question about switching to Oracle Cloud

We're a small company (about 10 people) in Australia and recently our general manager was approached by Oracle to switch to using their cloud away from AWS.

So far they've promised that it would be cheaper, more secure and that we will get brand contact with other companies using Oracle.

I've had a bit of a hard time finding good information to verify these claims. I can see from their website that it might indeed be cheaper, but hard to know if there's any other hidden fees. As for more secure I also couldn't find much info that wasn't from Oracle themselves. Plus we're not using a DB, we mostly use EC2, S3, a VPC and load balancer from AWS.

As for company connections, do companies really connect over the backend servers they use?

I'm trying not to be too negative, but I'm struggling not to think that my manager was just given the sales pitch for something that will at best be the same but with a different company.

Which CI tool?

Company is planning on getting CI but us developers lack prior experience with CI tools. We deal with higly confidential data and have a complex server architecture where some test environments can be accessed only through ssh from certain servers.

Recuirements:
On premises.
Podman compability.
Can send commands to a server through another server.

Bonus:
Mercurial support (we are considering migration to git)
Easy to learn, use and maintain.
RobotFramework and/or PyTest support.
Not too expensive.

We have been considering Jenkins or TeamCity and confirmed that both pass the requirements. While Jenkins is old & clunky and atm its mercurial plugin isn't actively maintained, it is free, unlike TeamCity which would ramp up in cost quickly since we'd need agents for all of our test servers.

A quick look through this sub gave me the impression that you love GitLab CI. Would it be able to ssh podman containers that run RFW tests and then show the results in UI?

Which CI tool would be the best option for our company?

Alternatives to Datadog ci visibility?

Hi all,
Just scoping for what people are using for their pipeline monitoring other than Datadog. We gave it a fair shot, it has some unique interesting features but it doesn’t quite match to what we’re looking for.

Can anyone point me to another direction?
Ideally foss for a PoC but enterprise is okay as well.

Brought on to help manage a WordPress website and now in charge of all tech... How do I explain to them that I need help or I will quit?

Like the title says, I was brought on as a freelancer to help manage a WordPress website. Since I took on that job, the CEO found out that I can do a lot more than work with WordPress, so he slowly fired everyone who was working on tech in the company and put me in charge of literally everything.

Somehow I became the CTO/CIO/Web Designer/Developer/Sys Admin/Customer Support/Tech Support and more.

This is a $30,000,000 company and my pay has increased significantly, but I no longer have time for any of my other clients.

No one in this company really understands tech and they think I can just magically make things happen an hour after they send a request. They don't realize how much can go wrong with just a simple software update, or that I am supporting 12+ people in the company.

How do I explain to them that I need help without blowing up on them? I don't want to lose this client, but I also don't want to lose my sanity or my other clients.

Oh and also - when 😸

Also, would love to know what you've done to get them? Or any tips for getting them?

Context: we're acquiring a company and they're based in EU. We'll be creating new accounts for all AWS, GCP and OpenAI in the US

We've also incorporated this year, so we're a fresh company.

Cannot authorizate AWS CodeArtifact from Vercel environment using private NPM package

Hey guys, I need some help here with a problem which I haven't been able to figure out neither through docs, gpt 4 or anything else.

I'm trying to set up the use of our private NPM package on vercel, but I always get an unauthorized message from Codeartifact on Vercel build logs.

____________________________________________________

Here is the error message:


 ERR_PNPM_FETCH_401  GET https://domain-codeartifactaccountid.d.codeartifact.us-east-2.amazonaws.com/npm/repositoryname/@package/subpackage/-/subpackage-versionNumber.tgz: Unauthorized - 401

No authorization header was set for the request.

These authorization settings were found:

u/package:registry=https://domain-codeartifactaccountid.d.codeartifact.us-east-2.amazonaws.com/npm/ninja-sdk///domain-codeartifactaccountid.d.codeartifact.us-east-2.amazonaws.com/npm/us-east-2/:_authToken=eyJ2[hidden\]

____________________________________________________

As you might see in authToken=eyJ2, the auth token is being sent. And I'm making sure it is updated on vercel through a local shell script every time I need to update the package or rebuild the app.

When I do the same thing locally on my machine, I'm successful at downloading the package, probably because I'm logged in to AWS Cli.

But sending the auth token to vercel and using it when building the app should probably be enough to download the package.

What am I doing wrong here? I tried using AWS cli on vercel but haven't been able to either.

You don’t need less data but better retention

https://shippingbytes.com/2024/06/12/you-dont-need-less-data-but-better-retention/

Back at when I worked at InfluxDB retention policy turned to be a gatekeeper because it is acutally not easy to decide how to move data in between "retentions".


Is it still the same for you? If not how you do it?

What tools do start ups with mixed cloud or on premise install req use besides k8s?

I am pretty experienced with k8s, having used it in production for the last 8 years or so.

I'm at the point now where I'd use k8s for pretty much anything more complicated than a static site, or a hackathon app. Right now I am working at a start up where we have been using it for our mixed cloud + edge app for the past 3 years and it has been working excellently for us as we often need to scale our clusters up and down, adding & removing accelerated hardware nodes.

Many people say k8s is too complicated for start ups, and for people who haven't paid the educational price of learning it, plus some form of IaC beyond k8s resource definition yaml files in git, I would definitely agree. It's not worth the innovation tokens.

However, because I have mostly only used k8s, I don't have a great knowledge of what options exist out there that provide a similar level of flexibility the way helm and custom resource definitions do. It's the thing that makes me like k8s the most; it would be much harder to set up an on premise postgresql installation with automatic fail over without kubegres, stackgres, crunchybase, etc. And wrapped with a terraform iac module, i can the deploy it in a bunch of different contexts if I would like. For example, I can configure images to come from a local registry in airgapped installations, versus on-premise with internet from our remote registry.

I know most traditional cloud based saas don't require this, but I am wondering what tools offer a comparable experience to k8s plus helm and CRDs for being able to deploy infrastructure in a production ready or near production ready fashion that would be suitable for startups that have on premise or mixed cloud installation requirements without experience with k8s & who want to "just get things done"

Greatly appreciate any insight into this people are willing to share.

What Stack Do I Need

Not sure if this is the right reddit for this, but I'm hoping someone can give me some insight.

I am in charge of helping to develop a portal where customers can log in and see certain details from a purchase.

I am anticipating needing to use a database system and am thinking I will need some kind of stack that will pull the information from that database.

We use NetSuite as a CRM and could potentially get all the information from it, but I'm worried about integration and the portal being clean and easy to navigate.

I want them to be able to click orders and see all the information available (like serial numbers), and other information that I would need to manually update for now.

Does anyone have experience doing this from NetSuite or would it be better to move it to a database and use some kind of stack to achieve the results wanted?

Tooling for generating helm charts and Argo app sets?

I have been struggling to wrap my head around our application sets and helm charts for a year now. My boss wrote them from scratch and what we do every time we have a new microservices or app is copy the last one and modify it. So far so good… However we have a very complex and flexible hierarchy of values, templates, and stuff that I don’t even know if they’re normal terms — trigger files and seed files, which a python script takes as inputs to generate the app set.

We have a multi-tenant architecture in regions all over the world in both AWS and Azure, and of course many environments, including the standard dev/qa/prod as well as cloud vs on-prem, so this is part of the reason for the open-ended nature of the way he designed things. It feels like a very loose (undocumented) framework that requires complete knowledge in. It’s pure gitops which I love, but often I find myself staring at a yaml and wondering what something does, how it fits in, and if it’s overridden somewhere else. I spend a lot of time recursive grepping, looking at Argo overrides (I hate the tag bubble format), and in general wasting time.

In a way this reminds me of Puppet hiera, but obviously more complex. The fix for that was Foreman with the UI that had taxonomy and inheritance. Is there anything like that for helm values? Is there any automation tool or popular framework that creates standardized app sets? (And helm charts?) Again the parallel would be something like creating an rpm from scratch vs having a polished script or tool like fpm to standardize the process. I’d love to have a Wizard-like tool guide me through the process. “Does your app need to talk to kube-API? No? Then you don’t need a dedicated service account. Let’s delete that from the chart so it doesn’t blow up when you don’t set values for it.” Etc.

I’m a smart guy but this really feels like the Wild West out here.
